How coronavirus spreads
Human coronaviruses cause infections of the nose, throat and lungs. They are most commonly spread from an infected person through:
- respiratory droplets generated when you cough or sneeze
- close, prolonged personal contact, such as touching or shaking hands
- touching something with the virus on it, then touching your mouth, nose or eyes before washing your hands
There are currently no vaccines available to protect you against human coronavirus infection.
If you have travelled to Hubei province, China, in the last 14 days, limit your contact with others for 14 days from the date that you left Hubei. This means self-isolate and stay at home. Contact the local public health authority in your province or territory within 24 hours of arriving in Canada.
The following steps will help to reduce contact with others:
- avoid individuals with chronic conditions, compromised immune systems and older adults
- avoid having visitors to your home
- avoid situations such as social gatherings, work, school, daycare, health care facilities and seniors residences
- limit taking public transit
In general, the following advice can help reduce the risk of infection or spreading infection to others:
- stay home if you are sick
- when coughing or sneezing:
- cover your mouth and nose with your arm to reduce the spread of germs
- dispose of any tissues you have used as soon as possible and wash your hands afterwards
- wash your hands often with soap and water for at least 20 seconds
- avoid touching your eyes, nose, or mouth with unwashed hands
- avoid visiting people in hospitals or long-term care centres if you are sick
People travelling to the province of Hubei should take precautions.
Health care or humanitarian workers caring for patients with suspected or confirmed coronavirus should use standard infection prevention and control precautions. This includes wearing appropriate personal protective equipment.
Risks of getting coronavirus

Canada also recommends that Canadians avoid all travel to the province of Hubei, including the cities of:
This recommendation is due to the heavy travel restrictions by Chinese authorities to prevent the spread of COVID-19.
At this time, it is unclear how easily this virus spreads from person to person.
Public health risk is continually reassessed as new information becomes available.
